i might have stuffed something up during my jailbreak. Instead of doing the proper iOS 4 update from itunes 9.2, i did “shift+restore” in itunes and chose iPhone1,2_4.0_8A293_Restore.ipsw file from my iHackintosh folder. I then went through the jailbreak process as mentioned above so is this going to do any damage to my iphone 3G? i was running on 3G firmware 3.1.2.
Yeah i know i did the whole thing backwards…
Thanks.
P.S while typing this message, i’m running the jailbreak process, it seems to be ok.
I’ve gone through the process twice and it doesn’t error but after the final phone reboot my 3G phone still shows I’m on 3.0.1. Do you need to be a specific OS prior to running this?
when selecting iOs 4 in first pop up screen in redsnow, it shows “unable to recognize specified ipsw.”
is this tutorial for 3G or 3Gs? the title says 3G but we’re asked to dld 3GS iOs 4 firmware.
i have a 3GS MC132ZA previously Blackrained then Spirited.

Hi, this option can used in 3gs with new bootroom, I have 3gs new bootroom and jailbreak it with spirit, and unlock it with ultrasn0w.
I need read yours comments, please tell me.
download the latest itunes first, which is version 9.2
Step 1 should be “Install IOS4 on your device first”

When I click on browse from redsnow there is no apple firmware to load from the download you provided. Only allflash and dfu?
